[Several Democratic Senators Send Letter Questioning Platform X's Preferential Treatment of Polymarket] Senators Catherine Cortez Masto, Adam Schiff, Jacky Rosen, and Richard Blumenthal have sent a letter questioning whether platform X is biased towards Polymarket. They point out that users cannot report Polymarket ads through X's standard interface, but can report other ads such as Kalshi. The letter alleges that X provides Polymarket with an unfair competitive advantage, benefiting President Trump and his family; Donald Trump Jr. has invested in Polymarket and serves as an advisor.
